J:COM Remote Control – Characteristic interactions

Problem Definition

J:COM, Japan’s largest telecom company in terms of number of users, announced the launch of its J:COM Smart Box set-top box. J:COM is always looking for the best balance between (technical) innovation and user convenience, partly due to the great variation within its target group (young to old). Here, the remote control forms the bridge between these users and the advanced graphical user interface (GUI). The key principles for the remote control are: compact, navigation by touch, and user-friendliness. That last requirement is quite strong, considering that the current product is seen by the consumer as very unfriendly due to the great number of buttons.


Due to its previous experiences with Japanese clients, D’Andrea & Evers has been able to respond to the need in terms of design. This had resulted in a characteristic design. The compact design is comfortable to operate with one hand yet also lies very stable on a flat surface. Because of the slider mechanism, only the most necessary functions are present initially. The two-colored setup increases the ergonomics by defining two clear groups.

The 3D shape of the touch disk provides tactile feedback. This enables the user to navigate securely without having to look at the remote control.
